“…Therefore, it indicates that phosphor may be applied as white light emitting phosphor in white light-emitting diodes. In the literature, it was determined that similar results were obtained when we compared our study with ZrO 2 :Dy 3+ luminescent materials synthesized by a different method [72][73][74].…”

In this paper, photoluminescence and thermoluminescence properties of ZrO2, ZrO2:Dy3+, ZrO2:Dy3+–Gd3+, ZrO2:Dy3+–Yb3+, ZrO2:Dy3+–Er3+, and ZrO2:Dy3+–Sm3+ phosphors synthesized by the Pechini method were investigated. The crystal structure, thermal properties, morphology, photoluminescence and thermoluminescence properties were investigated using XRD, DTA/TGA, SEM, PL and TL, respectively. The room temperature emission bands corresponding to 4F9/2→6HJ (J=9/2, 11/2, 13/2 and 15/2) transitions of Dy3+ ions were measured. The phosphors were analysed using Tm‐TSTOP, variable dose, and computerized glow curve fitting methods. Reusability, dose‐response, and fading characteristics were investigated. The phosphors have a natural TL emission that vanished by heating treatment. Moreover, new peaks with similar properties to the natural emissions were observed after high‐dose irradiation and long‐term fading experiments. The glow curves of the phosphors have thirteen individual peaks and many low and high‐temperature satellite peaks. The origin of the peaks is ZrO2 host material and doping with RE (Gd3+, Dy3+, Yb3+, Er3+ and Sm3+) does not lead to a new glow peak. The dopants cause drastic changes in individual peak intensities of ZrO2.The initial fading rates of all the phosphorus are relatively fast, but it slows down as time goes on.

“…The host material also has a significant impact on the optical properties of doped ions, and zirconia (ZrO 2 ) has attractive mechanical and chemical properties, such as a high melting point (2700 °C), stability to light and heat, chemical stability, optical transparency, high refractive index, and high hardness, compared to common halides and sulfides. 20,21 ZrO 2 also has a high dielectric constant, wide forbidden band width (5.0 eV) and a lower phonon energy (470 cm −1 ) 22,23 than YAG (800 cm −1 ), which suggest that it should be a more favorable matrix for luminescence. 20,24 The low phonon energy increases the probability of radiative emission from electron jumps in doped rare earth ions and reduces the energy loss from non-radiative multiphonon relaxation.…”

Spray Pyrolysis Technique; High-K Dielectric Films and Luminescent Materials: A Review

2018

View full text Add to dashboard Cite

The spray pyrolysis technique has been extensively used to synthesize materials for a wide variety of applications such as micro and sub-micrometer dimension MOSFET´s for integrated circuits technology, light emitting devices for displays, and solid-state lighting, planar waveguides and other multilayer structure devices for photonics. This technique is an atmospheric pressure chemical synthesis of materials, in which a precursor solution of chemical compounds in the proper solvent is sprayed and converted into powders or films through a pyrolysis process. The most common ways to generate the aerosol for the spraying process are by pneumatic and ultrasonic systems. The synthesis parameters are usually optimized for the materials optical, structural, electric and mechanical characteristics required. There are several reviews of the research efforts in which spray pyrolysis and the processes involved have been described in detail. This review is intended to focus on research work developed with this technique in relation to high-K dielectric and luminescent materials in the form of coatings and powders as well as multiple layered structures.
